UNITED STATES PATENT @Price VIIJLIAM BAKER MCGINNIS, OF NEVADA,MISSOURI.

STOVE.

SPECIFICATION forming part of Letters Patent No. 399,767, dated Ivarch19, 1,889.

Application led January l2, 1888. Serial No. 260,504. (No model.)

To all whom it may concern.

Be it known that I, WILLIAM BAKER INIC- GINNIS, a citizen of the UnitedStates, residing at Nevada, in the county of Vernon and State ofMissouri, have invented certain new and useful Improvements in Stoves;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which Io it appertains to make and use the same.

Figure 1 is a perspective view, partly broken away, of a heating-stovehaving my inveition applied thereto. Fig. 2 is a perspective view,partly broken away, of a cooking-stove having my invention appliedthereto. 3 is a vertical transverse section, enlarged, of the cartridgeswhich I propose to use in the heating-stove. Fig. 4 is a verticaltransverse section, also enlarged, of the cartridges which 2o I proposeto use in the cooking-stove.

Like letters of reference indicate like parts in all of the gures.

This invention relates to the use of what is commonly known ascartridges consisting,

2 5 essentially, of some fibrous or other absorbent material inclosed ina wrapper, casing, jacket, or net-work adapted to support such absorbentmaterial in convenient shaped and sized packages, which are to besaturated with some 3o combustible material. Prior to my invention suchabsorbent material has usually been supported upon a stationary gratingor other reticulated surface permanently attached to the heater. 3S

out distinctly in the claims hereof.

As illustrated in Fig. I, the stove is of some well-known form-as, forinstance, four sides, A A, top B, bottom C, with a door, D, and an 4ooutlet, b, for the products of combustion, with a suitable arrangementof draft, d, and,when preferred, a damper in the-pipe.

E c is a cartridge, which by preference has an outer casing or jacket,E', of sheet metal, having upon its upper wall or surface a series ofperforations, c c, with corresponding perforations upon two of itsopposite sides. as plainly shown in Fig. 3. The absorbent material,preferably asbestus, is shown at e in 5o Fig. l and at g in Fig. y

The nature of my invention will be pointed d d represent a support forthis cartridge, which in this instance consists of strips having angleends projecting inward from the side walls, A A, of the stove, combined,preferably, with a trough, A', having its bottom and side wallsperforated, as at d.

G g g represent a supplementary cartridge arranged in the lower part ofthe stove, the absorbent material g being preferably of asbestus. Asindicated in the drawings, this lower cartridge is of such size and formthat it can be easily taken out through the door of the stove; but forreasons to be hereinafter explained such construction is not essentialto the carrying out of my invention, and therefore I do not wish to belimited thereby, reserving the right to make this cartridge of such sizethat it cannot be taken out through the door, or, in fact, to make itintegral with the body of the stove. As shown in Fig. 3, this absorbentmaterial is arranged below some cross bars or wires g', which at theirends are attached to the sides of the car-' tridge, for the purpose ofmore effectually keeping the asbestus in place.

Of course, if it is not intended that the lower cartridge should beremovable, then these cross bars or wires may be dispensed with.

It is apparent that the holes a in the troughs facilitate the passage ofliquid from the upper cartridge directly down into the lower one,whereas were it not for these perforations such material wouldordinarily be conducted to the ends of the trough and run thence down aninner wall of the stove-a mode of operation which would be seriouslyobjectionable.

In Figs. 2 and 4 I have shown three cartridges constructed substantiallylike those of Figs. l and 3, except that the upper cartridge, l-I, hasits side wall next to the oven perforated its entire width in order touse the heat more effectively for the heating of the oven, it beingapparent that in a cookingstove perforations upon the opposite side ofthe cartridge would involve a waste of heat. Of course the upper wall ofthis upper cartridge is also perforated, as at h. The second orintermediate cartridge, I, is, by preference,

IOO

perforated only upon that side wall which is next to the oven. Thelower' cartridge, J, is, by preference, substantially like the lowercartridge in the heating-stove, and, like it, may be removable or not,at the will of the operator. In both instances I propose to provide theabsorbent material of the lower cartridge with an upwardprojectingtuft-like portion, K, for convenience in setting on fire the combustiblematerial.

From the above description it will be readily understood that myinvention may be operated in many ways which differ from any precedingone. For instance, in the heatingstove the upper cartridge may be madequite small, so that a comparatively small. portion of the wall of thestove shall be heated to such an extent as to radiate heat freely, andtherefore the stove will be suitable for use in moderately cold weather.Again, such of the combustible material as overflows or drips from theupper cartridge will fall upon and be retained by the lower one, whereit can be utilized for fuel whenever required, and when thus utilizedwill of course increase the heating capacity of the stove, whichincrease can be largely added to by filling the cartridge with similarmaterial or with different material, as the exigencies of the case mayrender desirable. So, also, in case the amount of heat produced by theburning of both cartridges should be greater than should be desired, theupper one can be removed, and thus an intermediate amount of heatproduced. The same results can be attained in the case of thecooking-stove, with the additional advantage that there are threecartridges used therein, of which the upper one is specially adapted toheat vessels or other cooking utensils placed on the top of the stove,while the intermediate one is adapted more particularly to heat the ovenby'reason of the flames being directly against the front wall of theoven, although, of course, part of the heat generated by this cartridgeserves to heat the top of the stove or anything placed thereon. So,also, in this cooking-stove the lower cartridge will receive and retainany drip or y overflow from either or both of those above it,

and the combustible material, which is in this manner or in any othermanner mixed with the absorbent material, may be burned either forcooking or for heating purposes only. The usefulness of this lowercartridge for adapting the stove for heating a room is greatly increasedby its location, it being obvious that for such uses the stove will berendered much more efficient by reason of this lower cartridge being sonear the bottom of the stove.

As there are many circumstances and conditions under which it isdesirable to maintain a moderate amount of heat in a stove for bricks offire-clay or other suitable material adapted to absorb heat from thecartridge during the period 'of combustion, and then give it offsomewhat slowly after the combustion has ceased by reason of theexhaustion of the cartridge. This mode of operation is exceedinglyuseful, not only in the heatingstove, but also in the cooking-stove,under circumstances where the .material which is being cooked by eitherboiling or baking requires to be subjected for a long time to acomparatively low degree offheat, as is frequently the case. Therefore Iprefer in both stoves that these blocks or bricks should be removable,in order to meet all the requirements which will be found under theordinary conditions of use. By arranging the cartridges in closeproximity to the side walls of the stove I insure the heat from themshall be given off by the said side walls of the stove in a much moreeffectual manner than it would be if they were separated at acomparatively great distance.

Vhat I claim is l. In combination with a stove, a series of cartridgesarranged one above another, one of the cartridges being removable,substantially as set forth.

2. In combination with a stove, a series of cartridges arranged oneabove another, and of which the upper one is removable, and the lowerone is adapted to receive and retain material falling from the upperone, substantially as set forth.

3. The combination, with a stove, of the perforated trough, thecartridge supported in the trough, and the cartridge below the troughadapted to receive material ilowing from the upper cartridge through thetrough, substantially as set forth.

4. In combination with a stove, a series of cartridges, one above theother, the upper cartridge having perforations in its upper surface andone side of its casing, the second cartridge having perforations in onlyone of its sides, substantially as set forth.

' 5. In combination with a stove, a series of cartridges, of which theupper one has perforations in the upper surface or wall of its i casing,and also in two or more of the sides of its casing, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.
